Select the image object with the mouse so that there are
handles (blue boxes) around the edges. The properties toolbar will change
to Image properties toolbar. Note: You can select objects
only when the Select tool
is in use.

Free hand draw on the image

Click the tool button. This
tool lets you draw on the image using a pencil-like tool. Choose the color
from the tool or the color
picker tool. Choose the pen
width from the tool.

Draw straight line on the image

Click the tool button. This
tool draws straight lines on the image. To use it, click where you want
the line to originate and then drag the tool by holding the left mouse
down until the "rubber band" is at the length and direction you want the
line to be. Let up on the mouse and the line will end at the current
cursor location. Choose the color from the
tool or the color picker
tool. Choose the pen width from
the tool.

Flood fill on the image

Click the tool button. This
function provides an area fill tool, sometimes called a "bucket fill",
because it's like dumping a bucket of paint across the image. It uses the
color chose from the tool or
the color picker tool.

When you click on the image with the tool, the Flood fill color
match dialog will appear. This let you choose the color distance to
match. 0 indicates strict color matching, and 255 indicates black matches
white.
